A computational model for analysing the stability of continuously welded rail track is developed by means of the finite element method in this paper, in which track panels including rails, ties, rail fastenings and ballast resistances as a whole system and non-linear deformation behaviour of rails under temperature stress are considered. Based on the model, the numerical computational formulae are induced and programmed. Influences of the lateral resistances of the ballast, invalid ties and curved track radius as well as initial flexural deformations on the stability of continuously welded rail track are investigated.
